7. The Chevy Volt

Gabor Ekecs for TIME

No-emission electric motors  which began the automobile revolution  are the technology of tomorrow for cars. But today's batteries can't support the typical driving experience. Chevy's Volt is a nice compromise. The sedan has an electric motor with a battery that can provide up to 40 miles (about 65 km) of range on a single charge. A gas engine kicks in to recharge the battery while you're driving. Since nearly 80% of us drive less than 40 miles a day, that means that unlike the Prius, the Volt could get drivers off gas altogether. The best of both worlds lands by the end of 2010.
